The Interplay Between Multisensory Associative Learning and IQ in Children

This study assessed the developmental profile of unisensory and multisensory processes, and their contribution to children's intellectual abilities (8- and 11-year olds, N = 38, compared to adults, N = 19) using a simple audiovisual detection task and three incidental associative learning tasks with different sensory signals: visual-verbal with pseudowords, novel audiovisual, and visual-visual. The level of immaturity throughout childhood was dependent on both, the sensory signal type and the task. Associative learning was significantly enhanced with verbal sounds, compared to novel audiovisual and unisensory visual learning. Visual-verbal learning was also the best predictor of children's general intellectual abilities. The results demonstrate a separate developmental trajectory for visual and verbal multisensory processes and independent contributions to the development of cognitive abilities throughout childhood.     

Manipulating Treatment Dose: Evaluating the Frequency of a Small Group Intervention Targeting Whole Number Operations

Treatment dose is an understudied aspect of treatment effectiveness. This study compared the frequency with which a small‐group mathematics intervention was delivered weekly (i.e., four times, twice, once) with a control condition while controlling for total duration. 101 at‐risk students in grades 2–4 were randomly assigned to a condition following universal screening and skill‐based assessments. Multilevel modeling was used to evaluate final score and growth on three measures. Results suggested that for the most proximal computation measure, treatment sessions occurring four times weekly produced clear benefits. On the application measure, students in all treatment groups outperformed students in the control condition. For the most complex computation measure, frequency was not a useful predictor. Grade was a moderating variable.     

System constraints on efficacious teacher behaviours in school-based suicide prevention initiatives; a qualitative study of teacher views and experiences

International concern about youth suicide has led to a growing consensus that schools are a potentially important location for suicide prevention efforts. The present study investigated the experiences and perceptions of teachers regarding a role in youth suicide prevention through semi-structured interviews which were analysed using Interpretative Phenomenological Analysis. Three themes are reported which contribute to an understanding of the construction of teacher efficacy in relation to a role in suicide prevention: baseline mastery, threats to efficacy and tension between personal and professional identities. The results indicate a mix of positive and negative experiences relating to personal, process and systemic factors. Positive elements were associated with the pastoral role. Negative experiences related to referral pathways and broader systems of care. Implications for the development of school-based suicide prevention programmes and for conceptualising processes of change in school systems are discussed.
